Review: Le transmetteur USB C - SPDIF est compatible avec l'iPad. Le son est transmis sans saturation ni coupures.
Review: This wonderful dongle was the perfect solution for listening to lossless, high-res Apple Music in bit-perfect transport to my WiiM Ultra-based sound system. Since I have a newer iPhone with USB-C port and an Apple silicon-based MacBook Air, I am able to hook up my iPhone (set to silent mode) to my WiiM's optical input and play high-res lossless Apple Music directly to my speakers, taking advantage of the WiiM's digital volume control (much finer than the iPhone's 16-step volume control), subwoofer integration, & room correction, and I am able to keep the iPhone charged, AND take advantage of the MacBook's iPhone Mirroring function to remote-control the iPhone/Apple Music from the comfort of my listening position 10 feet away. Awesome an highly recommended!

*by D***Y on 23 June 2023*

I'm using this to get digital audio out of a Raspberry Pi and into an SMSL SU-1 dac, and for that purpose it's exactly what I needed. I love how simple it is. I do think it's a tad expensive though, it's about the same price as an HDMI audio extractor which could do the same thing but this is a simpler device.. but whatever it works great. Side note: I've seen some reviews mentioning it doesn't work with Dolby or DTS. Although I haven't tried that, from what I know about optical audio there's really no reason it shouldn't work. It will not transcode your audio into Dolby or DTS though, as in it wont just output all audio that way. The software you're using must support sending those formats over optical audio (such as Kodi), and the file you're attempting to play must contain one of those audio formats. Once the software is configured to pass the audio through optical it should work.
